I found it fascinating how interdisciplinary it is and how it combines knowledge from different areas such as chemistry, physics, and engineering. Materials Science also resonated with me because it provides progress to various societal challenges.<\/p>\n During my master’s studies, I had the opportunity to do my master’s project as part of an Erasmus program in Dr. Stella Pedrazzini\u2019s research group. I quickly felt at home both in London and within the research group.<\/p>\n Can you tell us more about your research? <\/b><\/p>\n My research investigates the fundamental mechanisms behind Under Deposit Corrosion (UDC). UDC \u00a0poses significant challenges for industries relying on steam generators. These tubes are susceptible to UDC which occurs beneath deposits, leading to localized and unpredictable damage. Some key characteristics of this corrosion include the presence of porous deposit layers, high concentrations of chloride within these deposits, and the formation of complex laminated corrosion product layers.<\/span><\/p>\n To mimic real-world conditions in the lab, I expose low-alloy steel samples to a nickel chloride solution in pressurized containers, adjusting various parameters. This method aims to recreate the layered corrosion seen in steam generators. Understanding this type of corrosion is tough due to its unpredictable nature and the difficulties in experimenting, but it’s crucial for keeping steam generator components in good shape. Corrosion leads to expensive replacements and higher energy use in steel production, affecting finances and the environment. By studying this corrosion, we aim to improve operating conditions and reduce maintenance time.<\/p>\n What does a typical day involve? <\/b><\/p>\n Some days, I spend most of my time in the lab, conducting experiments and using advanced characterization techniques such as XCT (a way to see inside materials using X-rays) and SEM (a microscope that allows us to see tiny details on surfaces) coupled with EDX (a tool to identify elements in a sample) to analyse corrosion products. On other days, I am primarily at my computer, analysing data, answering emails, attending meetings, updating my industrial collaborator on the latest developments, reading papers to stay up-to-date, or working on writing publications or my thesis. I also work as a Graduate Teaching Assistant and am an active Departmental Student Ambassador.\u00a0<\/span><\/p>\n Can you tell us more about your research group? <\/b><\/p>\n What do you enjoy outside of your PhD? <\/b><\/p>\n Coming from Austria and having grown up in the Alpine foothills, I am passionate about spending time in the mountains. Whether hiking, skiing or mountaineering, being surrounded by nature helps me recharge. Living in London, I enjoy exploring the vibrant city. From visiting museums and galleries to attending theatre performances, there’s always something new and exciting to discover.<\/p>\n","protected":false},"excerpt":{"rendered":" Name: Parul Bishnoi Position: PhD Student in the Department of Materials Research Group: Dr Stella Pedrazzini Research Focus: Understanding the basic mechanisms of Under Deposit Corrosion (UDC), a major problem for industries using steam generators.

I’m part of two research groups. My main supervisor is Dr Stella Pedrazzini and my secondary supervisor is Professor Mary Ryan. My project is supervised by two successful women and I’m fortunate to work in a diverse and inclusive environment. Recently, some of our research group members, including myself, attended the TMS Conference in Florida.<\/p>\n
